The conclusion of the research is that we reject the null hypothesis and we conclude that the bag filling machine does not work correctly at the 426 gram setting.
<h3>How to solve hypothesis testing?</h3>
We are given;
Population Mean; μ = 426
Sample mean; x' = 433
Sample size; n = 13
Standard deviation; s = 29
significance level; α = 0.05
Let us define the hypotheses;
Null Hypothesis; H₀: μ = 426 g
Alternative Hypothesis; H_a: μ < 426 g
Formula for the z-score here is;
z = (x' - μ)/(s/√n)
z = (433 - 426)/(29/√13)
z = 0.87
From online p-value from z-score calculator, we have;
p-value = 0.1922
This p-value is greater than the significance value and as such we reject the null hypothesis and we conclude that the bag filling machine does not work correctly at the 426 gram setting.

Answer:
Montevideo
Explanation: i just know because i paid attention to the video..
If y=(x+2)(x+8)y=(x+2)(x+8)y, equals, left parenthesis, x, plus, 2, right parenthesis, left parenthesis, x, plus, 8, right paren

The characteristics of the graph that is displayed as a constant in the equation is the y-intercept
<h3>How to determine the
characteristics?</h3>
The function is given as:
y = (x + 2)(x + 8)
Set x = 0 to determine the constant
y = (0 + 2)(0 + 8)
Evaluate
y = 16
The above represents the y-intercept
Hence, the characteristics of the graph that is displayed as a constant in the equation is the y-intercept

I'm sorry but what book is this I can help you just tell me what book this is and I will see what I can do
Work and play are two usually conflicting things which should be carefully monitored and balanced in order for one to live a happy and successful life. Although work is necessary to be successful in life, too much work can result in exhaustion and loss of happiness in life. Working is needed, throughout one’s entire life, both to surpass obstacles and to achieve one’s goals; even students, whose jobs are school, are expected to work and reach towards their ambitions. However, play is necessary to maintain one’s happiness, and those who devote all their time to work and none to play often experience dissatisfaction and depression despite any and all achievements they attain. Human existence often focuses around enjoyment of life; in order to enjoy life, people must be allowed time to ‘play,’ to enjoy themselves even if it is not ‘productive.’ At the same time, playing all the time will leave no room for work, and this can result in loss of goals, achievements, and even other necessary things to survive. Work is needed to get through life, earn money, and be successful; yet too much work will result in one being overwhelmed and depressed. Playing is needed to live a fulfilling life and to be happy; yet too much play can leave someone without more necessary things or achievements to get them through life. Because of this, is can be concluded that someone must maintain a healthy balance between time spent working and time spent playing to be both happy and successful.
^ this is the most professional-sounding essay I could come up with off the top of my head... of course you could just utilize the main ideas if you want. Hope this helps at least in some way :)
